This tree produces red flowers that hang down from the ends of its branches in short and dense panicles. The flowers are covered in a fine, downy hair, giving them a soft, velvety look. During its flowering period, Firmiana colorata presents a spectacular sight with its orange-red flowers against its leafless state.

Growing between 10-20 feet tall, its hardy to zone 10. This tree requires full sun and organically-rich, sandy loam soil with plenty of moisture, yet it does not handle overwatering well.

They are covered in a fine downy hair, giving them a soft, velvety look. This flower is especially attractive to hummingbirds and butterflies, making it a popular choice for gardeners.

Young trees are often grown from a bulb or caudex and can even be grown as a bonsai plant. When planted in the ground, this tree grows into a large tree. During winter it often loses its leaves, and goes dormant. When flowering, it can be a stunning sight with its orange-red flowers against its bare branches.
